CIRCULATING DYEING-MACHINE.

Application filed July 14, 1913.

To all whom it may concern:

Be it known that we, VVALTER IV. SIBsoN and THOMAS ALLsor, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Circulating Dyeing: Machines, whereof the following is a specifioation, reference being had to the accompanying drawings.

The invention relates more particularly to circulating dyeing machines, wherein dyed liquor is forcibly circulated through the dyeing receptacle, and the direction of the flow of the liquor is capable of being changed.

An object of the invention is to provide means whereby the ratio between the times of flow in reversed direction may be varied.

A further object of the invention is to provide means for causing a uniform flow of the dye liquor throughout various parts or the dyeing receptacle.

A further object of the invention is to provide an improved form of propeller for causing a circulation of the dye l1quor,wh1ch propeller is so shaped and constructed as to tend to produce a uniform flow of the dye liquor throughout the entire receptacle, with as little churning or undue commotion 1n the dye liquor as possible.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

In the drawings, which show by way 01' illustration, one embodiment of the invention, Figure I, is a longitudinal section through a dyeing machine embodymg our improvements. Fig. II, is a sectional view on the line II-II of Fig. I. Fig. III, is an enlarged detail showing a section through the propeller. Fig. IV, is a sectional view on the line IV-IV of Fig. I. Fig. V, is a sectional view on the line V--V of Fig. II. Fig. VI, is a detail in plan showing the sectional adjustable cam for operating the valves. Fig. VII, is an edge View of the same. Fig. VIII, is an enlarged detail in plan showing one of the supporting bars for the articles to be dyed. Fig. IX, is a sectional view through the same, showing the article supported in dotted line.

tion, and has side Walls 2, 2, and end Walls 3, 3. This receptacle is divided by a cross partition 1, so as to provide a main dye chamber 5, and a circulating chamber 6, in which is located the propeller for causing the dye liquor to circulate into and through and out of the main dyeing chamber. This partition 4-, terminates short of the bottom of the receptacle so as to form a passage 7. The partition likewise terminates short of the top of the receptacle so as to form a passage 8. A second partition 9, is spaced from the end wall 3 of the receptacle, and extends from end to end of the propeller chamber. This propeller chamber is formed by longi tudinal partitions 10, 10, which join the partition 1, with the partition 9. The lower part of the propeller chamber is closed by a partition 11, having an opening 12,.therein, controlled by a valve 13, while the upper side of the propeller chamber 6, is closed by a cover or partition 14, having an opening 15, therein, controlled or closed by a valve 16. In each end wall of partition 10, 10, there is an opening 17 which admits the dye liquor to the propeller chamber. The valve 13, is pivotally supported by a suitable bracket, and is so constructed that when the same is in. open position, as shown in Fig. I, the passage 7, is connected with the propeller chamber, while the passage underneath the bottom of the propeller chamber is closed. When the valve is in this position the dye liquor is admitted through the opening 17, in the end walls of the propeller chamber, and is discharged through the opening 19, and through the passage 7, into the main dye chamber. When the valve 13, is closed and the valve 16, is opened, then the dye liquor received into the propeller chamber through the opening 17, will be discharged through the opening 15, and through the cage or support for the material to be dyed, and thus into and through the main dyeing chamber. The raising of the valve 16, practically closes the passing of the dye liquor over the top of the propeller chamber, and the closing of the valve 13, opens the passage underneath the propeller chamber, so that a complete circulation of the dye liquor in either direction may be secured.

The valves 13, and 16, are connected by three links 18, so that when one valve is open, the other is simultaneously closed, and vice versa. The upper valve is raised and lowered by a link 19, which is pivoted at its pper end to a rock arm 20, fulcrumed on a bracket 21, carried by the fixed cover 22, extending across the dyeing machine directly above the propeller chamber. This rock arm is provided with a second rock arm 23, which is operated upon by a cam 24. The cam 24, is mounted on the shaft 25, which carries a gear 26. This gear 26, meshes with a worm 27, carried by a shaft mounted in a bracket 23. The shaft also carries a second worm wheel 29, which meshes with a worm gear 30, carried by a shaft 31, which is actuated by a belt wheel 32. A hand wheel 33, normally free on the shaft 27, may be clutched to the worm wheel 29, for rotating the same manually. The shaft 32, actuating the worm wheel 29, is mounted in suitable brackets 34, and this is the main driving shaft for the machine.

The cam 24, is made in sections as clearly shown in Figs. VT and VII. The section 35, is rigidly attached to the shaft by a set screw 36, while the section 37, is clamped to the section 35, by a clamping bolt 38, which extends through segmental slots 39, and 40, formed respectively in the sections. By loosening the clamping bolt 38, the sections may be adjusted so as to increase or decrease the concentric portion thereof. This cam is turned in the direction of the arrow in Fig. I, and as the incline face 41, engages the rock arm 23, the said arm will be forced to the right, as viewed in Fig. I, thus opening the valve 16, and closing the valve 13. As long as the nose of rock arm 23, rests on the concentric surface of the cam sections 35 and 37, the valves would be held in this position. As soon as the extreme end 42, 0f the concentric portion of the section 37, passes the rock arm, it would at once swing to the position shown in Fig. I, owing to the weight of the valves, and the valve 16, will be closed while the valve 13, is opened.

By the shifting of the valves, the direction of the circulation of the dye liquor is reversed. Assuming that the shaft 25, rotates at a uniform speed, it will be apparent that the time of flow in one direction may be varied relative to the time of flow in the opposite direction. For example, if the shaft rotates once every ten minutes, the cams may be so adjusted that the flow in one direction will be for a period of four minutes, while in the other direction a period of six minutes.

Located within the propeller chamber is a propeller 43, which as herein shown, is formed in two sections so as to accommodate the central link which connects the valves. These two sections are identical, and are both rigidly attached to a shaft 44, mounted in suitable hearings in the side walls 2, 2, of

the machine, and this shaft 44., is rotated by a belt wheel a5, which cotiperates with a belt wheel 46, on the shaft 25.

As shown in Fig. 11, of the drawings, we have provided a series of belt wheels 45, of difierent diameters, and corresponding belt wheels 16, so that the relative speeds of the shafts 25, and 4 1, may be varied. In certain classes of work, it is desirable to have a very rapid flow of the dye liquor, while in other classes of work, it is desirable to have a slower flow of the dye liquor. This can be readily accomplished by the shifting of the belt on to the desired pulleys, and thus the travel of the propeller increases or decreases for a given speed of the main shaft 25. The propeller consists of two end disks which are spaced and which are provided with blades 47. These blades as herein shown are spread from side to side, but are set at an angle to the radius of the propeller wheel. It is obvious, of course, that from certain aspects of the invention these propeller blades may be otherwise shaped and otherwise positioned We prefer, however, the form shown in Fig. III, and above described, as the flow of water entering through the openings at the ends of the propeller chamber will be entered by the propeller blades in a wedge-like manner, which facilitates the uniform and free flow of the same from the. propeller chamber. e preferably provide angular partitions d8, which change the shape of the propeller chamber to further facilitate the free and uniform flow of the dye liquor without undue churning or commotion in the liquor.

At the bottom of the main dye chamber 5, we have provided a perforated bottom 49. Beneath this bottom are three distributing plates 50, 51, and 52. The plate 50, extends substantially the entire length of the main dye chamber, and has a portion of its extreme end perforated as at 53. This distributing plate 51, extends a less distance, and has a portion of its extreme end perforated as at 54, while the plate 52, extends still a less distance and has a perforated portion 55. These plates extend from side to side of the vat or receptacle, and will cause the dye liquor to be uniformly distributed throughout the entire length of the main dye chamber 5, and to uniformly circulate up through the perforated bottom 49.

The main dyeing'chamber is closed by a removable cover 56, which is formed with suitable lifting eye bolts 57. Suspended from the COVQI' 56, is a perforated supporting plate 58. Extending crosswise of the plate 58, are bars 59. These bars support the articles to be dyed. Each bar, as clearly shown in Fig. TX, is V shaped in cross section, and is perforated as at 60, to permit the dye liquor to circulate through the bar. By the above construction of supporting bar the article to be dyed will be held with the portions thereof each side of the bar well spaced, and the only points in which the bar contacts with the article will be at the upper edges 61, and 62, of the metal forming the bar. l/Ve are able by this construction of supporting the bar to expose substantially all of the surface of the article being dyed to the flow of the dye liquor.

The cover 56, is clamped on the side walls of the dyeing chamber, so as to prevent the same being raised by the flow of the dye liquor on the supporting plate for the articles being dyed, byclamps 63, which are pivoted to the cover and are formed so as to swing underneath pins 64, carried by the side walls of the receptacle. The clamps are also provided with a weighted arm 65, which tends to hold the clamp in engagement with the pin 64:, and the cover clamped on the receptacle. These clamps at each side of the receptacle may be connected so as to be simultaneously operated.

From the above construction it will be apparent that we have provided a dyeing machine, wherein the flow of the dye liquor may be made substantially uniform throughout the entire region of the dyeing chamber, and wherein the time of flow of the liquor in opposite directions may be varied. We have also provided other features of construction which tend to facilitate the uniform dyeing of the articles, and wherein a wide range of adjustment may be had for adapting the dyeing machine for varying conditions.

It is obvious that minor changes in the details of construction and arrangement of parts may be made without departing from the spirit of the invention, as set forth in the appended claims.
